Problems solved by technology

Due to the structural design of the hardness tester itself and the fit of the tooling, it is easy to cause the center of the measuring probe and the center of the measuring object to be out of the same center position, especially when measuring a spherical workpiece, such as when measuring a steel ball, when there is a load, due to The measuring probe is not perpendicular to the measuring center of the workpiece, which will easily lead to the deviation of the steel ball and the measuring probe, and the hardness measurement data will be distorted. In serious cases, the probe will be broken or the internal lever mechanism will be deformed and bent, and other instrument damage will occur.

Abstract

The invention discloses a special clamp for a Rockwell hardometer measuring tool. The clamp comprises an installation pedestal, a platform fixing pedestal and a cylindrical workpiece measuring platform, wherein, the installation pedestal is connected with a lifting bar, the middle of the installation pedestal is provided with a first groove in which the platform fixing pedestal is arranged, the middle of the platform fixing pedestal is provided with a second groove in which the cylindrical workpiece measuring platform is fixed, and the whole clamp is positioned and fixed through jack-up of the platform fixing pedestal resulting from close cooperation of the installation pedestal and the lifting bar. Compared to the prior art, the invention has the following advantages: since a measuring platform is adjusted and fixed in one shot, it is not needed to calibrate center points for each measuring, thereby enabling simple operation, convenience and efficiency; no deviation of objects to be measured is guaranteed in measuring and a measuring probe and the center of the objects to be measured are kept consistent, thereby ensuring authenticity and accuracy of measured data of hardness and avoiding damage of equipment like hardometer probes, internal levers, etc.

Description

technical field [0001] The invention relates to a Rockwell hardness tester, in particular to a special fixture used on a tooling specially used for measuring hardness on a Rockwell hardness tester. Background technique [0002] At present, the Rockwell hardness testers sold on the market basically only provide one measurement platform for hardness measurement due to the consideration of the universality in the industry, such as Figure 4 As shown, it includes a lifting rod 1 and a measuring platform 19, which are mainly used for hardness determination of metal products. Due to the structural design of the hardness tester itself and the fit of the tooling, it is easy to cause the center of the measuring probe and the center of the measuring object to be out of the same center position, especially when measuring a spherical workpiece, such as when measuring a steel ball, when there is a load, due to If the measuring probe is not perpendicular to the measuring center of the wor...
